K sage to the mixer and wherein it is converted Referring to .the drawings, ldesgnates the into a gas. This duct is preferably formed shell or casing of a battery 'of burners, such by a removable plate 16, secured over a de- Ioo 5o shell being composed of upper and lower pression formed in the top plate of the casplates connected at their ends and sides and ing. The oil-supply pipe 18 opens into the duct at one end, and in this pipe is a cage 19, wherein is located a valve 20, the function of which is to automatically check the backfiow of the gas, such valve, however, not entirely cutting E the forward flow of the oil, so that as soon as the flow back is checked the valve will immediately resume its normal p'ositiou and allow a free passage. To the other end of the duct is connected one end of a coil 21, which opens into tube 5 of the mixer. Beneath this coil is a cup 22, wherein may be placed alcohol or its equivalent to serve as a torch or primer in starting the burner, the heat therefrom convertingr the oil in the coil into a gas before it reaclles the mixer.

In practice after the `initial conversion of the oil into gas the latter will pass out through the delivery end of tube 5 of the mixer, en-

training the air through inner tube 6, and in passing into the supply-tube 3 additional air is drawn in lhroughsuch tube as well as through the surrounding air-tube 7. The gas passing into the chamber 2 will find its exit through the diagonal openings formed by the slots 9, and passing upwardly through such openings around the burner-tube 12 will entrain air upwardly through passage-way 13 between such tubes and the walls of the burner`openings, with the result that before the gas reaches the perforated tiange of the burner it will be well and heavily charged with air, insuring thereby the production of a blue llame. Air is Ialso drawn inwardly by the llame at the point of combustion through the central opening 14 of the burner. The heating of the top plate of the burner-casing being eected by the time the torch or primer is burned out, the oil is converted into a gas in its passage through the duct 15.

From what has been said it will be observed that by the described arrangement I provide for the thorough admixing of oxygen with the oil gas, such admixture occurring at several different points before the gas reaches the burners, and that in addition thereto a further supply of air is drawn in by the flames through the central openings of the burners. Thus all the gases are consumed and a perfectly-blue aine of a high degree of heating capacity is obtained.

` In Fig. 4 I have shown the application lof my improvement to asingle burner. In this form the oil is admitted to apipe or tube 23, wherein it is converted into a gas bythe heat of the burner, and its outlet-opening is controlled by an inner air-tube 24, such outletopening being connected by a tube 25 to a cylindrical casing 26, having a lower inner surrounding baffle-plate 27, causing the gas to pass upwardly between casing 26 and au inner casing 28, having upper tianges or lateral fingers 29, resting on the outer casing 2G. Above the casings is a perforated plate or screen 30, where the ignition of the gases occurs, the heat of such gases servin g to contin uously generate the oil into gas in its transit through tube 23. This form of burner may be used for heating fiat-irons or for any desired purpose where one burner is alone sufticient.

The advantages of my invention are apparent to those skilled in the art. It will be specially observed that by means thereof a battery of burners of any size may be employed and a perfectly-blue llame produced by each burner of the series. This is due to the'fact that in addition to the thorough admixture of the oxygen with the gas each burner lhas its own independent air-supply.

I claim as my invention- 1. In a hydrocarbon-burner having a gasconverting chamber and means for supplying air to the gas, a casing beneath the point of ignition having an air passage-way into which the gas enters and wherein the air and gas are intermingled before ignition, and a second air passage-way centrally of the burner through which air is supplied to the flame, as set forth.

2. In a hydrocarbon-burner having a gasconverting chamber and means forsupplying air to the gas, a casing having upwardly-directed ports through which the gas passes below the point of ignition,an air-chamberinto which such ports discharge and wherein the air and gas are intermingled before ignition, and a second air passageway Within the burner for supplying air to the flame, substantially as set forth.

3. In a hydrocarbon-furnace, a shell or casing having a battery of openings extending therethrough, the wall of each opening having a slot or slots facing upwardly, a burnertube for each opening forming between itself and the wall of the latter an air-passage wherein the air and gas are intermingled before ignition, a second air passage being formed in each burner for supplying air to 'the flames, means for converting the oil into gas, and a mixer opening into the chamber of said shell, said mixer having means for intermingling the air and gas before entering such chamber, substantially as set forth.

4. In a hydrocarbon-burner, a shell or casing having a battery of openings, the wall of each opening having a slot or slots facing upwardly, an oil duct or passage-Way extending across the top of such shell or casing, a gassupply tube leading into the chamber of said shell, a mixer connected to said duct or passage-way and having an air-inlet tube or tubes,l said mixer opening into said gas-supply tube, and burners located in said battery of openings and forming between themselves and the walls of the openings air-passages wherein the air and gas are intermingled before ignition, as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
